Question

(ii) With the aid of diagrams and appropriate equations describe eth fluid behaviour of blood and how the action of red blood cells and plasma proteins contribute to these properties.

Answer 1

Blood by definition,it like fluid, it movies through the circulatory system and vessels. Coming to human it includes blood cells,cell fragments called platelets...etc

Now we talk about red blood cell those are responsible for carrying O2 and CO2 .

Coming to plasma this is the main component of blood.and mostly water consists. Not only water it contains proteins,ions,nutrition and some wastes also mixed in. These are 55% percent. In human blood.

Now we will  take white blood cells these are part of the immune system and function in immunity response.

Coming to platelets these are responsible for blood clotting.these are 45% in human blood.

Now we see plasma.

Fig :-1   ⬜⬛⬛⬜⬜

The middle one is plasma Plasma :- 1 water.

2 ions.

3 proteins, wastes , gases.

And the last one is red blood cells.

Normally the fig num 1 is test tube so the middle one plasma, the last one is red blood cells. And white blood cells in between them.

Plasma can be isolated by spinning a tube with high speed.

The denser of cells and platelets move to the bottom of the tube, then red layers will from.froming a yellow layer to.

It consists 90% of water and 10% is made up of ions, proteins.....etc.

Red blood cells are erythrocytes and specialised cells containing through out the body .

It is 7 to 8 micro meter size.

The lungs, red blood cells take up oxygen, and send to all body parts and release the o2  to surroundings tissues. It is important in transport of co2, waste product from tissues.

Three red blood cells life span is 120 days.

If any damaged RBC are broken down in the liver and spleen, and New one will produce in bone marrow.

Platelets are 2to 4 micro meter in diameter.

It is also called thrombocytes.

WBC is also called as leukocytes, it makes up less then 1% of the cells in blood.
